Imagine a paper-thin shoe with an upper whose only support comes from threads. This is Flywire Nike’s revolutionary lightweight support system. Flywire is a performance architecture that utilizes very thin and incredibly strong fibers to support the foot alllowing Nike designers to create some of the lightest footwear to date. Flywire consists of high-density nylon fibers placed in carefully chosen locations, precisely where the foot needs it. These fibers act like an extra layer of epidermis containing light, man-made tendons and also shave weight off the shoe.  Flywire also provides a supported, locked-down fit reduce foot slippage within the shoe, something that wastes a significant amount of energy per stride.

Nike designers engineered the upper of the Zoom Aerofly LX with the strap and zipper design that Liu Xiang is accustomed to. Knowing that Liu Xiang’s was looking for added protection for his right foot, the designers increased the thickness of the padding at the heel to increase support around his ankle.

For the outsole, Nike designers studied the performance needs of Liu Xiang. A powerful and explosive hurdler, Liu Xiang hits the ground hard with each stride and must spring up quickly after impact. To meet these needs, Nike’s designers utilized specially made mico-carbon soles to provide firm frontal support. Knowing that Liu Xiang lands on his forefoot following a hurdle, the designers used micro-carbon material in the forefoot to help provide forefoot support. Working closely with the Nike designers, one of the things that he likes best is that there are only 5 spikes at the front, reducing the weight of the shoe. The ergonomically placed spikes  also helped to reduce pressure on the forefoot and increase traction. In response to his specially designed spike, Liu Xiang said that “the uppers fit the foot perfectly and are incredibly light and comfortable.”

Since Liu Xiang began working with Nike in 2002, Nike established a special task force to design spikes for Liu Xiang, including the design and research of all of Liu Xiang’s footwear and related products.  To meet his needs, designers travel all over the world following Liu Xiang to the sites of his competitions and practice meets in order to communicate with him. Liu Xiang also travels to Nike’s world headquarters for an in-depth discussion with the design team about his sneakers.
